Hey Chris,
>From a previous yak-shaving-adventure, I've dabbled in building Proj and Geos for Android, because they were dependencies of Spatialite, which I'm using for an app. That resulted in a homegrown build system based on docker, aptly named: Building for Android with Docker. It is meant as a repository for working build sets for various native libs. I didn't previously have GDAL in there, but decided to give it a shot and add it, to see how much effort was required. Not much as it were. I've added GDAL now, with a compile-time dependency for Proj, so it shouldn't be more of a hassle than simply checking out the repo and then "make gdal". Instructions for how to extract the libraries from the container, is in the readme. Here's the link to the repo: https://github.com/rhardih/bad I've built and tried a very simple Android app, and added some of the source from https://gdal.org/gdalinfo.c.html, to see if the libs actually loaded up and Proj was supported. It seems to work just fine. You can find the example app, source and output here: https://github.com/rhardih/gdal-proj-android So far I've only used this project for personal consumption, and I need to do a lot of grooming and test/writing before it's really ready for public use, but this might solve your problem in this instance.
